I am developing an application in which i want to encode the Spanish text. But the problem is that,it doesn't encode the special characters such as á, é, í, ó, ú, ü,Á, É, Í, Ó, Ú, Ü,Ñ,ñ . How can i do this?i want to encode-decode the spanish text.

For international support using simple UTF-8 encoding to encode/decode your data should be enough.

Utf-8 has a beautiful capability to be able to read ASCII with one byte, as ordinary ASCII, and Unicode characters with 2 bytes. So it's able "to shrink" when it's necesary.

For complete C# documentation look on UTF-8

EDIT 

  Encoding enc = new UTF8Encoding(true, true);
  string value = " á, é, í, ó, ú, ü,Á, É, Í, Ó, Ú, Ü,Ñ,ñ "; 
  byte[] bytes= enc.GetBytes(value); //convert to BYTE array 

 //save in some file 

 //after can read  from the file like
 string decodedString = enc.GetString(byteArrayReadFromFile);

  • i tried utf-8 and base64 but it failed to encode non-ascii characters – dd619 Sep 25 '12 at 06:54
  • I think you don't use it in a right way. Can provide some code ? – Tigran Sep 25 '12 at 07:10
  • //encoding using utf-8 public static string EncodeTo641(string toEncode) { byte[] toEncodeAsBytes= System.Text.UTF8Encoding.UTF8.GetBytes(toEncode); string returnValue= System.Convert.ToBase64String(toEncodeAsBytes); return returnValue; } //decoding strings public static string DecodeFrom64(string encodedData) { byte[] encodedDataAsBytes= System.Convert.FromBase64String(encodedData); string returnValue =System.Text.UTF8Encoding.UTF8.GetString(encodedDataAsBytes); return returnValue; } – dd619 Sep 25 '12 at 07:30
  • @dd619: you have to use manipulation methods present in that class in order to correctly write/read data in that format. Declaring it's not enough. – Tigran Sep 25 '12 at 07:32
  • @Tigren: when i pass " á, é, í, ó, ú, ü,Á, É, Í, Ó, Ú, Ü,Ñ,ñ " as encode it gives á, é, í, ó, ú, ü,Ã, É, Ã, Ó, Ú, Ãœ,Ñ,ñ as output – dd619 Sep 26 '12 at 09:31
  • @dd619: I see you translete the text to 64bit string, why do you need that? – Tigran Sep 26 '12 at 09:35
  • i just tried ur code as string decodedString = enc.GetString(bytes); – dd619 Sep 26 '12 at 11:40
  • but I don't use 64base conversion, why do you. I translate your string into byte array, fter save it into file, and read it from the file to see that all caharcters are the same I saved before. – Tigran Sep 26 '12 at 11:42

ok,I am answering my own question ,Hope it will help someone; to print spanish or any other non-ascii character in the given string replace all non-ascii characters by their unicode escape character set E.g repalce á by \u00e1 And then simply print the string.

i.e

string str="árgrgrgrááhhttá";
str=str.Replace("á", "\u00e1");
